The automatic classification engine (cgexec, cgclassify, pam_cgroup)
classify tasks. It is useful for an application to know where it has
been classified. I propose to add a new API
cgroup_get_current_controller_path() that returns the current
classification directory for the specified controller. One can easily
add on and build new API that will return paths of all mounted
controllers, but I want to start with something simple and useful.
I've also added a bunch of test cases for the same purpose.
Test output
# ./pathtest.sh
Test FAIL, get path failed for controller cpuset
Test PASS, controller cpu path /default
Test PASS, controller cpuacct path /default
Test PASS, controller memory path /default
Test FAIL, get path failed for controller memrlimit
I mounted just cpu, cpuacct and memory, thus the path for cpuset and
memrlimit could not be found (as expected).
